Thanks John! I've not messed around with all of this in some time... Everything has _really_ changed. Does anyone have a pointer to how to run QEMU for Armv7 and install the Tier 2 armv7 image? I found: http://ftp.freebsd.org/pub/FreeBSD/releases/arm/armv7/ISO-IMAGES/13.2/ which seems to have the install image... but I can't find any instructions on how to do an install... If someone has fired-up QEMU for this and happens to have the list-of-what-to-do, it would be terrific... otherwise I'll start stumbling through to see what I can figure out. - Thanks! - - Dave R. - > > I had to set up a jail to test 32 bit ARM on a 64 bit host.

Because both 32 and 64 bit progams use the same intepreter pathname they can't both work. > -- rivers@dignus.com Work: (919) 676-0847 Get your mainframe programming tools at http://www.dignus.com
